123w ago - Just under a week ago we reported on news of a successful PS3 downgrade from 3.55 to 3.41 Firmware, however, it ended up not being reproducible until a PS3 3.55 to 3.41 Firmware Downgrader arrived today courtesy of solidpsycho through a guide from AmazingLarry.
To quote: Here is a patched 3.41 that allows you to downgrade. I patched the info0 to 356, and I also used Warrens method to bypass the br drive during the update. I have tested this on both of my PS3's and haven't run into any problems.
3.55 Downgrade has been confirmed on both FAT and SLIM consoles.
Please note you CANNOT use these files if you bought a PS3 that came stock with FW 3.50. DO NOT DO IT. STOP NOW.
124w ago - Update: KaKaRoToKS has now confirmed that the PS3 3.55 downgrade is no longer possible, tweeting the following: "sad news.. downgrade worked, but not reliable, only works with one of Xtse's ps3s, but can't reproduce it.. I'm going to look for another way. nope, it only works on one machine, even if same model, it doesn't work on it. No idea what's different about it..."
Today KaKaRoToKS has confirmed via Twitter news of PS3 downgrade success from version 3.55 to 3.41 PlayStation 3 Firmware.
This confirmation comes just days since his PS3 Custom Firmware surfaced and under a month after the PSGrade free PS3 Downgrading hex codes arrived for version 3.5 and below consoles, followed by Sony revoking lv2diag.self file_1 and patching PS3 downgrading in the PS3 Firmware 3.55 update.
Here is his Tweet, to quote: "First downgrade from 3.55 to 3.41 successful, Thanks to Xtse! Method not yet ready for the masses...
126w ago - While we know that PS3 Firmware 3.55 patches the ability to downgrade your PlayStation 3 console, this weekend Dukio reports that brand new 3.50 PS3 Consoles may also not be downgradable as well.
To quote: "Amid reports of new PS3 Slims owners who have no luck in downgrading their PS3 consoles, i would like to warn those people who like to buy a new PS3 console and Jailbreak it by looking at these suggestions below:
1. Beware of pre-installed 3.50 firmwares PS3 Slims, most people have no success in downgrading their console with any methods online on these consoles. The new batch of PS3 slims might have been given some kind of protection in order to prevent it from downgrading to an earlier version of firmware. So, please take note of it.
2. If you still want to buy a stocked 3.50 firmware console or that there are no other version of PS3s available in your area, i suggest buying on earlier CECH models, like CECH-25xx and clearly stay away with CECH-251x! You might also want to check the console with this sticker instead of this. Notice the bold part? dekoslav has confirmed that the bold one can be downgraded."
127w ago - Previously we reported that PS3 downgrading hinders Blu-ray movie playback along with some work-arounds while markjtarr began a Poll on working/non-working drives post-downgrade, and today Project Blu-ray seeks to restore functionality using feedback from PlayStation 3 downgraders.
To quote from PSGroove (linked above): "They are asking anyone with a PS3 to run an app they have developed, which will dump certain files related to Blu-Ray playback.
It does not matter if the Blu-ray problem is affecting your console or not, your files are still needed for analysis. Once analyzed, this should lead to a permanent Blu-ray playback fix!"
From the included ReadMe file: One of the most exciting recent developments is the ability to downgrade PS3s to previous firmwares. Unfortunately this has proven to have an unexpected side-effect for certain older ("phat") PS3s:
After downgrading, systems with 256MB of flash RAM (NAND) lose the...
128w ago - Since the release of PSGrade there have been lots of PS3 Downgrade Hex Codes for all types of devices, and today Matrix15 and xXJohannXx of Logic-Sunrise.com (linked above) have posted a PIC18F hex code and guide which can be found below.
To quote, roughly translated: After leaving the downgrade for the different clones based Atmel microcontroller, the service mode is finally available to the dongle-based ICP such as ZBN SPI USB V1, V1.1, V2 , or PS3liberator NbzgroovePIC v1.0 at PICDEM bootloader is available.
The downgrade process is similar to any other dongles, you'll need: downgrade-files (http://www.logic-sunrise.com/telecharger-172586-downgrader-files.html)
1 - Upgrade your NbzgroovePIC or module ZBN with the update for the downgrade. (The update is done the same way that a jailbreak for maj.)
